To provide metrics monitoring, the MapR Control System (MCS) requires the collectd and OpenTSDB components to be installed. Metrics monitoring is part of MapR Monitoring, which also includes log monitoring. MapR Monitoring components are available as part of the MapR Ecosystem Pack (MEP) that you selected for the cluster.

You can apply a patch by using the MapR Installer, by using the command line (a manual process), or by using a MapR Installer Stanza.
